chodi bez problemu, chipset je podporovan v kernelu
Doporucene volby pri kompilaci kernelu:
[*] Memory type range registers (MTRR) - pro prehravani videa
[*] VIA82CXXX chipset support - pro udma na secondary kanalu
[*] Use PCI DMA by default when available
[*] UHCI (Intel PIIX4, VIA, ...) support - pro USB
[*] ACPI support
nebo
[*] Advanced Power Management BIOS support
[*] Enhanced Real-Time Clock Support - pro prehravani videa

hint:
procesory Cyrix a IBM pouzivaji CPU->SRAM linear burst =>
specialni jumper a povolit v BIOSu (defaultne zakazano!)
modifikace VA503A ma 3xDIMM,4xPCI,1xISA,1xAMR a az 2MB L2 cache
Infraport lze dobastlit pomoci HSDL-1000 (~200Kc), konektory k USB (2*5 pinu) lze dokoupit (~100Kc).
